The tubes are stuck into Legolas's neck, and as they begin to pull free and the liquid runs down Legolas's skin and clothes and across Thranduil's hands, blood begins to run down his skin. But Legolas doesn't flinch, doesn't pull away, so Thranduil keeps pulling, until it's far enough split that he can pull it away from the younger elf's neck. He drops it, and it rings as it hits the ground, and then circles back around again. He's bleeding, but Thranduil is not much of a healer, and regrets it as he reaches out. His face is twisted, an expression rarely seen.
